Apple Watch

U.S. watch sales fell the most in seven years in June, one of the first signs Apple Inc.’s watch is eroding demand for traditional timepieces.

Retailers sold $375 million of watches during the month, 11 percent less than in June 2014, according to data from NPD Group. The 14 percent decline in unit sales was the largest since 2008, according to Fred Levin, head of the market researcher’s luxury division.
